EDWARD 'KENER, .13., or BUFFALO, NEW YORK.

INCINERATOR.

Application filed August 27, 1921. 'seriariro. 496,043.

To all whom it may concern:

Be it known that I, EDWARD KENER, J r., a citizen of the United States, residing in Buffalo, in the county of Erie and State of 'New York, have invented new and'useful other refuse by means of burning the same.

The object of the invention is to provide a convenient gas burning household incinerator in which the refuse is heated at the upper surface thereof, so as to not necessitate the heating of the entire mass of refuse before combustion is enable to commence. A further object --of the invention is to produce an incinerator which is not liable to the danger of explosion by reason of the gas flame becoming extinguished, which reduces loss of efliciency by radiation to a minimum, which automatically keeps the gas burning at the most eflicient part of the body of refuse, while the latter is being slowly consumed, which is readily demountable, and in which the operating partsv are not likely to burn out or become clogged.

In the accompanying drawings:

Figure 1 is a front elevation of the complete incinerator. Figure 2 is a vertical section thereof taken on line 22, Fig. 1. Figure 3 is a horizontal section taken on line 3-3, Fig. 2. Figure 4 is a fragmentary vertical section through the lower part of the incinerator, taken on lines 4l4, Figs. 2 and 3. Figure 5 is a detail vertical transverse section through the. diffusing plate and filler plate. Figure 6 is a fragmentary front elevation of a modified form of incinerator. Figure 7 is a vertical section thereof taken on line 77, Fig. 6. Figure 8 is a detail of the modified lifting mechanism taken on line 88, Fig. 7.

Similar characters of reference refer to like parts throughout the several views.

matically descends as the refuse is consumed and whose lower face is suitably provided with gas through a vertical telescopic gas pipe communicating with a central station-- ary hollow grate bar. The .side grate bars may be shaken by suitable handles arranged at the front part of the incinerator. Air from the ash pit travels upwardly between the inner heated wall and the outer insulat-. ing wall of the incinerator, thereby not only furnishing the combustion chamber with heated air, but,'in addition, insulating the high temperature zone and also preventing the inner heated walls from burning out.

The main body or insulating walls of the incinerator preferably consist of the outer vertical plates 10 and 11, which are .provided on their inner surfaces with insulating asbestos sheets 12 and 13 that are separated preferably by a dead air pocket or space 14. Similarly, the roof of the incinerator consists preferably of horizontal plates 15 and '16 and lined with insulating asbestos sheets 17 and 18 which are separatedv by a dead insulating air space 19. The whole body rests upon the usual hori zontal floor or base plate 20 which is provided with su'itable'upper flanges 21 and 22 for retaining the difi'erent vertical walls and insulating sheets in proper position relative to each other. i I

Secured to the inner lower face of the inner wall 10 is a laterally projecting annular supporting shelf 23 preferably provided at its inner side with an upwardly extending flange 24 and further provided with a number of arcuate air apertures 25 disposed outside of said flange 24 and adjacent to the inner wall 10. Supported by said lateral shelf 23 and disposed in spaced relation to the inner wall 10, is a heated wall 26 which forms the main combustion or incinerating chamber in which the refuse 27 is adapted to be consumed. Beneath-the combustion chamber is arranged the usual ash pit 29 to which access is gained by the customary hinged ash door 30, which is provided with the adjustable air inlet slits 31 which permit the necessary air for com bustion to flow into said ash pit. Some of this air is permitted to travel upwardly through the aforesaid air apertures 25 and thence through an annular passageway 32 which is situated between the heated wall 26 and the inner plate 10 of the outer inuse 27 through the air diluting holes.33. Also some of this air. continues upwardly in the said annular passageway 32 and emerges from the upper .end thereof, and impinges against the lower, downwardly in clin'ed face of an annular deflecting plate 34. In both cases, the airlin the-said passageway acts in two capacities as it flows upwardly, that is, it is heated by contact with the wall 26 so as to readily combine with and, thereby completely 'oxydize any partially oxydized'gases (such as carbon monoxide) or any rising solid material in the co bustion chamber (such as soot). Also th s heating of the rising air currents in passage way32 causes the inner heated wall- 26 to be sufliciently. cooled downas to be not liable to be burned out or melted by the high temperatures existing within- -the combustion chamber. In addition to this, the rising current of cool air also largely prevents radiation from the said inner heated wall 26 out to the inner insulating Plate 10. v

Pivotally mounted in the lower part of the inner, heated wall 26 is ahorizontal central stationary grate bar 36 and a pair ofhorizontal oscillatory grate bars 37, 37 disposed parallel to and on each side of said central stationary grate bar. All of these grate bars are hollow and are provided at their forward end with bell shaped air inlets 39 and suitable gas control valves 40 which controlthe flow of gas from a Ihain supply gase pipe 41 into-the several air inlets 39.'

The outer or oscillatory grate bars 37 are provided at their forward ends with upwardly extending arms 42 to whose upper,

' bifurcated-ends are. pivoted shaker handles 43 each of which is pivoted relatively to said arms 42, in a plane which passes through the longitudinal axis of its companion oscillatory grate bar. In ordinary practice, there is a tendency for these handles to' drop forwardly and project inconveniently into the room. This fact has been made use of beneficially in this improved incinerator, by providing a means whereby each of said handles is positively held back properly against the wall of the incinerator,

when-and when only, the companion oscillatory grate bar is in a definite and most de- This beneficial result. is"

sirable position. obtained by means of a pair of spring brackcent to each shaker handle 43 and are adapted to resiliently seize opposite sides" of the shank of each of said shaker handles when the same has been first movedlaterally into alignment with the space intermediate of the jaws of said resilient brackets 44 and f then manually forcedsrearwardly between same in the position shown by full linesin .the drawings. -Thus,'not only is each of said shaker handles held positively rearwardly'.

out of the way but in addition the companion oscillatory grate bar isheld in its proper centralized position when at rest, i. e., at the conclusion of the shaking operation.

The central stationary grate Joar 36 has its rear end reduced somewhat in diameter and is provided at its extreme rear end with a horizontal lower flattened seat 45. This extreme rear end of said stationary grate bar is received within the bore of a suitable socket 46, the lower face of WllOSB 'bOI'G is suitably flattened to accommodate the aforesaid flattened seat 4 5.. The forward hollow part or, bore of said stationary grate bar opens centrally. and upwardly into a" combustion opening 47 Adjacent to and on both sides of said opening, the stationary grate bar is provided with aflattened upper face 49 upon which detachably rests a telescopic gas pipe 50, the lowermost and largest section of vwhich is provided with a forwardly extending horizontal flange 51 and a rearwardly extending horizontal flange 52,.

grate bar 36'. The upper end of said shank is enlarged to form a retaining head 56 whose lower face bears downwardly against the upper face'of the realgas pipe flange 52.

Received within the forward slot 53 of the front'hor-izontal flange 51 is an upwardlyextending detaining lug 561 provided with a suitable hole to receive a removable transverse securing pin 57. By thisc0nstruct10n,

readily removed from the stationary grate bar 36 by merely first removing the pin 57,

then lifting the front flange51 and slidingsaid lower telescopicvgaspipe section forwardly ing head 56.

Said telescopic gas pipe is composed of a the lower telescopic gas pipe section may beout of engagement with the retain" number of vertical, coaxially arranged sections of diminishing size, each of which is provided at' its lower outer end with aperipheral flange 59 and provided at its upper inner end with an inner annular flange 60.

Furthermore, the upper peripheral corner of each pipesection is suitably beveled at 61 for the purpose of deflecting the refuse 27 away from the joints between companion pipe sections. I

To the upper end of the uppermost telescopic gas pipe section are adjustably sefcured 'a number of supporting L-shaped. I brackets 62, each of which is provided with 1 a vertical slot to permit vertical movement of said bracket relatively to said gas pipe sectionand is adapted to be secured in place by a suitable cap screw 63. To the upper arms of said brackets is secured a conical upwardly tapering burner plate 64, whose lower or concave side is spaced some distance above the upper end of the uppermost gas pipesection, so as to permit a flow of gas from saidpipe section to the whole under face of said burner plate. The latter is adapted to at all times, rest upon the upper surface of the refuse so that the only contact between said plate and the refuse is at the peripheral edge of said plate. It is at this same peripheral edge also that the gas at the under surface of said burner plate comes into contact withthe air in the combustion chamber and is thereby enabled to burn with a gas flame in the usual way.

This burning occurs upon the upper surface of ,the refuse and for this reason the com- 'bustion of the same is continuousand regular by reason of the fact that only the uppermost strata of refuse need be dried out, and these strata thereby brought to the point of sufficient dryness for self combustion before the lower strata need be also dried out or otherwise effected.

It is assumed that for ordinary use, the only gas which is to be lit or ignited is that at the periphery of said burner plate, the gas in the oscillatory grate bars 37 being only ignited when it is desired to heat the lower body of refuse, which condition occurs under unusual circumstances, such for instance, as when the refuse consists largely of very large pieces of material having a very high water content such as watermelon rinds, The burning of the refuse from the upper surface downwardly which is the normal condition has another important advantage in that while the refuse is drying (previous to the time when it begins to oxydize rapidly) it, of course, gives off both combustible gases and obnoxious fumes. In this improved incinerator, these combustible gases are ignited and thereby utilized-in theupper part of the incinerator chamber and the obnoxious gases are forced to pass through the flame area 'at the periphery of the-burner plate and thereby become chemically disintegrated into solid matter, con 1-" bustible gases which are'instantly consumed and also some final gases of combustion like carbon dioxide which are odorless and not poisonous and no more obnoxious than the ordinary gases eminating from acoal or oil burning boiler or, gas stove which gases largely consist of carbon dioxide.-

To ensure-that a sufficient space intervenes between the periphery of the burner plate and the upper surface of the refuse,

a number ofjdepeiidin spacing lugs 67 are formed on'the-p'e'r'ip cry of said burner plate, Safety means arealso' provided for" absolutely ensuring that the gas in the upper, gas-pipe section will at all times'have a clear pathway to the combustion chamber. This is accomplished by the use of a number of gas conducting tubes 69 which are secured to the lower tapered face of the burner plate, their inner open ends being disposed over the upper end of the upper, telescopic gas pipe section while their outer open ends are disposed at the periphery of said burner plate.

Arranged above the burner plate and resting upon a suitable annular flange 70, formed on the upper bore of the inner heated wall 26, is a stationary downwardly tapering diffusing plate 71 which is pro-' vided with a plurality of perforations 72.

:plate is cut out to form a large clean-out hole 7 3, to which access is gained by opening the main refuse filling door 74 to the position shown in full lines in the drawings and which is suitably hinged to the front wall of the incinerator. Formed in the periphery of this clean-out hole 73 is a pair of diametrical outwardly extending removal notches 74 Removablyresting upon the lower part of the upper concave face of the diffusing plate, is a circular covering plate 75 which is preferably downwardly tapered similarly to said diffusing plate and is centrally caused to be located in its proper central position thereon by means of a number ofv upstanding placement lugs 76 formed 'integrally upon said diffusing plate and adapted to bear against the peripheral edge of said covering plate 75. Vhen it is desired to remove the latter, for cleaning purposes, it is merely necessary to, lift the same, then tilt on one edge and remove downwardly through the aforesaid removal notches 7 4. Centrally the said covering plate 75 is provided with a hole 77.

Passing vertically through'said hole is a vertical elevating chain 7 9 whose lower end is suitably secured centrally to the'burner 3 wheel 82 and terminates in a suitable securing 'ring 83 which may. either be hooked to The r a central hook 84 whenfit is desired to allow the upper surface of the refuse automatically is lowered by burning), or said ring the burner. plate 64, to freely descend'fas 12 83 maybe secured to an outer hook 85 when it is desired to hold said burner plate in its elevated position when, for example,

fresh refuse is beingfed into the incinerator through the. main filling door 74.

The upper part 'of the rear or inner end of said air tube 81 is removably covered by an air difl'using lid 86'which is perforated by a number of air orifices 87. This Construction permits pure air to be drawn in through the air tube 81- and distributed in diffused streams into the hot flue gases which pass. up a smoke pipe 89, such diflusion being in accordance with the best established practice in present day incinerators. An additional advantage gamed by this particular construction however is that the horizontal portion of the elevating chain 79 (which would ordinarily be the first to burn out) is located right in the midst of the I streain of cool air'which flows through the air tube and thus is effectually cooled and prevented from burning out.

Each of the outer or oscillatory hollow grate bars 37 is provided on each of its lower longitudinal sides with a longitudinal row of gas apertures 90 preferably spaced at regular intervals.v Disposed above each and every gas aperture 90, and secured integrally to the main body of the. companion osclllatory grate bar 37 is a laterally extendlng supporting arm 91 whose upper face 1s preferably substantially horizontal (when the grate bar is' in its central position, as shown).

The lower face or edge however of each "lat 'eral supporting arm 91 is inclined and extends downwardly and laterally outwardly away from itscompanion gas aperture 90. By this construction, the liquids of condensation which fall on the grate bars, are

drained down and away from the gas aperture 90, the liquid being thereby caused to drip from the lower outer cornersof said supporting *zarms.

In operation, the

refuse which is to be destroyed in an moffen'sive manner, isfed into the incineratorthrough the main filling'door 74, after the burner plate 64 has been :suf-

ficiently elevated by means of the lifting securing hook-85 during this filling operachain 79, whose securing ring 83 may, if desired, be temporarily slipped over the outer tion. The central gas valve 40 is then turned on and the lightingdoor 92 is pushed to one side thereby exposing the lighting aperture 93, by which means the gas under the burner plate 64 may be lighted readily and the lighting door 92 again swung back into place. As the garbage or refuse is gradually consumed, the upper surface of the same lowers and, with it, the burner plate64. The

vertical relative distance between the upper sectioneof the telescopic gas pipe 50 and the burner plate is adjustable by reason of Set screws 63. The gas is prevented from becoming extinguished by reason of a number of gas conducting tubes 69. If it'is desiredtoburn the refuse from the bottom also, theouter gas valves 40 are turned on and the gas in the oscillatory grate bars 37 ignited.

If desired for any reason whatsoever the telescopic gas pipe 50 may be readily de-' tached from'the central stationary grate bar 36 by merely removing. the pin 57. To re move the hand-hole, cover-plate 75, the same need be merely tipped, up and removed gownwardly through the removal notches 4. z This incinerator disposes of refuse Without any odorously objectionable gases being present even in the. smoke pipe thereof: It utilizes to the full the. economical and eflicient ability of the refuse to aid in its own destruction when properly dried out and ignited. It rather cannily compensates for mechanical defects or laziness in human nature by insisting that the human operator must either have the oscillatory grate bars 37 in their proper position or else suffer the aesthetic and otherwise uncomfortable projection of the shaker handles 43 out into the room. It is impossible to burn out the elevating chain '79'because its horizontal part is alwavs air' cooled andits verticalpart some distance away from the flaming gas (which burns under at the periphery of the burner plate). At the same time this cooling of the horizontal portion of said lifting chain 79 involves a construction which is used for the additional purposeof feeding diluted pure air into the combustion chamber adjacent to the smoke pipe 89 thereof. Pure air is also fed into said combustion chamber from the air chamber 32 through a number of air outlet holes 33 which are disposed in vertical, as well as horizontal rows, so that fresh pure air is always pres-- which in this modified construction rotates about a horizontal axis. The said elevating chain then passes vertically upwardly again in proximity to the front outer face of the incinerator, and. has its extreme upper end.

secured to the hub of a capstan'drum 101 1 which is suitably secured to a capstan shaft 102. The rear end of said capstan shaft is suitably journaled in the front face of the incinerator, while the forward end of said shaft is suitably rotatably supported in a bearing. bracket or two legged cleat 104 which islikewise secured to the front face of the incinerator by rivets 105 or otherface of the cleat 104 and the front or outer end of the capstan drum 101." Secured to the upper face of the cleat 104 is a small bracket, or angle iron 109 to whose .outer vertical face is pivoted at 110 a ratchet dog 111 whose lower arm is adapted to project downwardly through a suitable opening 112 i in the upper flange of the aforesaid cleat and engage at its lowermost end or point with the ratchet teeth of the ratchet wheel 107. The upper arm 113 of said ratchet dog extends some distance above the upper flange of the cleat 104' and is provided at its extreme upper end with an overhanging enlargement or weight 114 whose center of gravity (in the full line position) is on the same side of the ratchet arm of said ratchet dog 111. Thus when the dog is in its full line position the capstan drum 1 01 is-prevented from rotating in a clockwise direction (lookingrearwardly). However, if the center of gravity of the said weight 114 is shifted to the right,

i. e., on the other side ofthe dog pivot 110, then the said dog will be held in the dotted line position and out of engagement with the ratchet wheel 107. This latter is the position of the dog when the handle 106 is being rotated in a clockwise direction for the purpose of lowering the burner plate 64. On the other hand, when it is desired, to lift the burner plate, the weight 114 is thrown to the left and the handle 106 rotated man ually until the said burner plate has been elevated as much as desired, at which point it will be automatically held by the coaction between the dog and the ratchet wheel. It

should be particularly noted that this construction requires no springs and that the dog is automatically self'holding its locked or its unlocked 'POSlillOIl by the throwing of the weight 114 toward the one direction or the other.
